UPDATE: Body found in GH Township has been in the water about two years

An autopsy on a decomposed body that was discovered in Lake Michigan Sunday night in Grand Haven Township revealed few clues toward its identity.

Ottawa County Sheriff's Department officials Lt. Mark Bennett said an autopsy performed Monday morning at Spectrum Health Systems Blodgett Campus revealed the victim was an adult 20 to 40 years of age and that the body had been in the water about two years. The autopsy, however, did not determine a cause for death or its gender.

Bennett said additional forensic tests will be performed. The investigation is being hampered by the extensive decomposition of the body. He said various portions of the body are missing and authorities recovered one article of clothing. There were no identification items, such as a wallet.

The body was discovered by a beach walker near the shore at around 6:30 p.m. Sunday about one-fifth of a mile north of Lake Michigan Drive. Deputies were summoned to the scene and found a body that had been in the water "some time."

Bennett said there are no unsolved missing person reports in this area and he does not believe the Grand Haven Township body had any connection with a female body discovered last Wednesday near Pentwater. Bennett said there have been cases of bodies floating across the lake from Illinois or Wisconsin.

Persons with any information are being asked to call the department at (616) 738-4687, or Silent Observer at (616) 842-1400.
